SPECIFICATION forming part of Letters Patent No. 610,433, datedSeptember 6, v1898.

Applicant niet my 18,4 189s.

To @ZZ wiz/0m, it moby concern.-

Be it known that I, CHARLES I-I. CURTIS, a citizen of the UnitedStates,residin g at Derby, county of New Haven, State of Connecticut,have invented a new and useful Automatic Bufng-Machine, of which thefollowing is a specification.

My invention has for its object to provide an automatic bufng-machinewhich shall be adapted to buff all sizes and styles of articles withinthe capacity of the machine,which will do its work in the finest mannerpossible, and which shall require the services of but a single attendantin feeding the machine and removing the finished articles.

With these ends in viewI have devised the simple and novel bufngmachineof which the following description, in connection with the accompanyingdrawings; is a specificafl tion, numbers beingused to designate theseveral parts.

Figure l is a side elevation; Fig. 2, a front elevation Fig. 3, a planview, the standards being in section on the line .fr as in Figs. 1 and2; and Fig. 4 is a detail View, on an enlarged scale, of mechanism Vforraising each holder in turn into a position in which the article carriedthereby may be acted upon by the bufIing-wheel.

1 denotes the bed, 2 legs by which itis supported, and 3 standardsextending upward from the bed, said parts comprising the frame! work ofthe machine.. I Wish it distinctly understood, however, that the specialcon-V struction of the framework of the machine is not of the essence ofmy invention, but that the details may be varied to suit the require-Vments of any special use for which the ma chine may be intended or thetaste of the builder. u

4 denotes the buffing-wheel, which may be of any ordinary or preferredconstruction-` for example,` a rag-wheel, so called. 1 The buhingwheelis carried by a shaft 5, jour naledin bearings G upon avertically-adjustable lcarrier 7. The ends of the carrier engage slots 8in the standards,and the carrier, and with it the shaft andbuftlng-wheel, is adapted to be moved toward or from the feedwheel,`presently to be described, as may be required in use, bymeans of screws9, carried serial No. 681,036. (No man.)

by across-piece 10, extending from one standard to the other." Thescrewsare free to be turned in the cross-piece, but are held againstvertical movement therein, so that rotation of the screws will raise orlowerthe crosspiece and the buffing-wheel. Power'is applied to themachine by means ofa belt (not shown) passing over a pulley 1l on shaft5. l2 denotes another pulley on shaft 5, from which a belt (not shown)extendsto a pulley 13 on a shaft 14, journaled in boxes 15, in thepresent instance under the bed.

16 denotes a pinion on shaft 14., which meshes with a gear wheel 17 on ashaft 1S, journaled in boxes 19, in the present instance under the bed.At the inner end of .shaft 1S is aworm 20, which meshes with a wormwheel21 on a vertical shaft 22, journaled in a hub 23 on the bed.

, 24denotes a feed-wheel carried by shaft 22, which rotates in a plane.at right angles to the plane-of the bufng-wheel. l

The articles to be buffed are carried by holders 25, each holder beingcarried by a plunger 26, adapted to engage any o ne of a series ofcorrespondingly-shaped openings 27 in the feed-wheel, in which it isadapted to slide freely. The lower end of each plunger is rounded, as at28, (see Fig. 4,) to adapt it to engage and be raised by a rounded shoe29, which lies below the feed-wheel and in the vertical plane of thebufling-wheel. Each holder is provided with a clip or clips 30 to holdthe article to be buffed, and as each holder in turn comes under thebuffing-wheel it is raised into position, so that the article carriedthereby will be acted upon by the bufng-wheel. The instant, however,that .the plunger has passed the shoeit drops down to its normalposition, as clearly shown in Fig.4. The shape of the shoe is of coursenot of the essence of my invention and may be varied to suit therequirements of special articles that are to be buffed. I have shownboth ends of the shoe as so shaped as to provide an easy incline for theplunger to ride up and to ride down and have shown the ceuter asslightly depressed. These, however, are mere details of construction andmay be varied to suit the special use to which the machine is applied.By making the shoe IOO highest on opposite sides of the center I providethat the holder and the article that is being buffed shall be raised atthe instant it passes under the edges of the buflng-Wheel,

so as to receive the full action of the edges of the bufiing-Wheel asWell as of the center. The shoe is provided on its under side With anear 3l, which is pivoted to a plunger 32, which is adapted to engage acorrespondinglyshaped opening 33 in the bed, in which it slides freely.The ends of the shoe may be raised or loweredl to give any requiredadjustment thereto by means of set-screws 34 in the bed, as clearlyshown in Fig. 4. It Will be seen that by providing simple and convenientadjustments for both the bufiing-Wheel and the shoe and by making theholders removable, so that other sets of holders may be substituted, ifrequired, I insure an almost unlimited range of usefulness for themachine in bufing articles of varying shapes and sizes.

Having thus described my invention, I claim-f l. The combination Withthe bufing-Wheel, of a feed-Wheel, holders on the feed-Wheel forarticles to be buifed and means for raising each holder at the instantit passes under the bufng-Wheel, said holders being also removablysupported by the feed-Wheel and adapted to be lifted therefrom orreplaced during the rotation of said Wheel.

2. The combination With abufng-Wheel, of a feed-Wheel, holders by Whichthe articles to be buffed are carried and which are provided withplungers extending through openings in the -feed-Wheel and a shoeadapted to b'e engaged directly by the lower end of each plunger at theinstant the corresponding holder passes under the buffing-Wheel so thatan article upon the holder is placed in position to be acted upon by thebufting-Wheel.

3. The combination With a bufting-Wheel, of a feed-Wheel havingopenings, holders provided with plungers Which engage said openings andare guided thereby and an adjustable shoe lying in position to engagethe plungers successively as the holders pass under the buffing-Wheel.

4. In a machine of the character described the combination With abuffing-Wheel, of a feed-Wheel, removable holders on the feed- Wheel bywhich the articles to be buffed are carried, each holder having aplungerextending through the feed-vvheel, a shoe lying in position to beengaged by said plunger successively as the holders pass under thebuffing-Wheel, said shoe being provided with an ear Which is pivoted toa plunger passing loosely through J[he bed and set-screws 34 by Whicheither end of the shoe may be raised or lowered` 5. The combination withthe bufing-Wheel, of a feed-Wheel lying at right angles thereto, holdersin `the feed-Wheel each of which vis provided with a clip to hold anarticle to be buffed, and an adjustable shoe by which the holders areraised in turn as they pass under the buffing-Wheel, said holders beingremovably supported by the feed-wheel and adapted to be lifted therefromor replaced during the rotation of said Wheel.

In testimony whereof I affix my signature in presence of tWo witnesses.

CHARLES I-I. CURTIS.
